The Committee for Joint Action, CJA says re-denomination of the cedi will not address the fundamental problems inherent in the economy.It disagrees with the Bank of Ghana that the main advantage of the exercise is that of portability.According to the CJA, there are various means of achieving portability without re-denomination.Addressing a news conference in Accra, the spokesperson for the group, Bernard Mornah noted that increasing the use of cheques for transactions and the introduction and mass use of credit cards can also achieve portability without full-blown re-denomination.The group said the exercise is purely an administrative and economic measure but the government is making a huge propaganda blitz with it.The group expressed concern about the timing of the re-denomination exercise especially when the Bank of Ghana has announced that Ghana is to join the Eco currency zone in 2009.Another concern expressed by the group is the inability of the Governor of the Bank of Ghana to provide an estimate of how much it would cost to print and circulate the new currency.
